TABLE-BED FOR SEWING-MACHINES.

Specification of Letters Patent.

Patented July 4, 1916.

Application filed April 12, 1915. Serial No. 20,628.

T 0 all whom it may concern:

Be it known that 1, CHARLES H. MEKEEL, Jr., a citizen of the United States, and a resident of the city of St. Louis and State of Missouri, have invented a new and useful Improvement in Table-Beds for Sewing- Machines, of which the following is a specification.

This invention relates to power sewing machines, particularly such as are mounted upon a work bench or table, and driven from a power shaft located below the table by means of a belt which passes through the table. a

The invention consists in a hollow metal bed or base constituting a drip or splash art of the sewing machine and by means of which the sewing machine is secured to the table.

The invention further consists in the guard for the belt pulley and in the modification of the pulley whereby it can be rotated by hand from outside of the guard.

The invention further consists in the constructional details of the bed whereby oil is prevented from staining the cloth or other work being operated upon.

Further details of the invention will appear in connection with the .description of the device illustrated in the accompanying drawings; and what the invention consists in is more particularly pointed out in the appended claims.

' In the drawings, in which the same reference characters designate like parts in the several views, Figure 1 is an isometric view of a sewing machine bed embodying the invention; Fig. 2 is a cross-section of the same through the pulley guard, on the line 2-2 in Fig. 3 Fig. 3 is a longitudinal midsection of the same on the line 33 in- Fig. 2, showing the outline of the lower part of the sewing machine in ,dot and dash lines; and Fig. 4 is a cross-section of the sewing machine pulley, showing the alterations therein to adapt it to the pulley guard, the original outline of the pulley being shown in dotted lines.

The bed or housing for the base of the sewing machine as shown in the drawings comprises a shallow box having a bottom .11, and sides 12 which preferably are integral with the bottom. The ends 13 are preferably integral with the bottom and with the sides, in order to insure that there shall be no leaky joints between them. The right end has an outwardly ofi'set portion 14 which has a hole 15 through its bott l 1m for the driving belt of the sewing mac me.

A swinging guard 16 is pivoted to the end of the base over thehole for the driving pulley, and forms an upward continuation of the ofiset portion 14 of the right end wall. The top portion of the swinging guard 16 incloses the upper end of the eccentric strap or pitman which operates the reciprocating parts of the sewing max chine. In its open position the swinging guard also catches any oil which may be splashed toward the rear of the machine if the latter is operated with the guard thrown up.

Between the lower edgeof the swinging guard and the top of the offset portion 14 of the right end wall is an opening 17 in line with the pulley shaft. The pulley 18 is provided with a knob 19 which projects outside of the base and guard as shown in Fig. 3. The pulley guard is secured in closed position by means of a wing nut 20 and bolt which engage in a slot 21 in the front side of the offset portion 14 of the right end wall. A lip 22 along the lower edge of the pulley guard projects inside of the top edge of the offset portion 14 of the bed to keep oil from splashing out and to deflect it down inside of the bed.

The base 23 of. the sewing machine is held to the work table 24 by means of long screws 25 which go through the table and bed and screw into the under side of the The bed has tubular.

projections 26, and washers 28 are arranged between the washers 27 and the under side of the work table, whereby the bed and the table by tightening up the screws 25. A hole 29 is made through the bottom 0 the bed for the operating chain or rod which connects up the stitch controlling mechanism on the sewing machine to a foot pedal beneath the work table. A lip 30 surrounds this hole on the upper side to prevent oil from following through the hole,

sewing machine are both secured to the anda similar lip surrounds the hole on the under side of the bed and prevents oil which passes through the hole from getting out on to the top of the table.

The offset portion 14 of the bed surrounding the hole 15 for the belt pulley has downwardly extending side walls 31 which project through the work table. The front edge of the downwardly extending side walls which surround the hole projects down farther than the rear edge, and a groove 32 around the inside of the lower edge of the side walls 31 conducts all the oil which follows down the side walls to the front edge thereof, where it can either drip off or be caught and. carried away without getting on the driving belt.

A cover 33 is hinged to the top of the left end of the bed, and closes the open top of the bed all around the top 34-. of the base of the sewing machine. This cover 33 has its front edges overhanging the front side of the bed to keep oil from splashing out. The free end of the cover 33 is secured to the right end of the bed by a wing nut 35 and bolt which engage a slotted tongue 36 on the end of the cover which overhangs the right end of the bed.

It is evident from an inspection of the drawings that the device provides a complete housing for the moving parts of the sewing machine which need to be kept well oiled, and that said parts are easily accessible'for cleaning and oiling by lifting the pulley guard and top cover of the bed. Moreover, the pulley guard can be kept in its normal position over the pulley without interfering with the rotation of the pulley by hand as occasion demands.

The invention is not restricted to the par.- ticular shape and arrangement of the parts of the device shown in the drawings.

I claim the following as my invention 1 1. A bed for sewing machines comprising a bottom adapted to rest upon and be secured to a table, openings in said bottom, and means for preventing oil from passing through said openings on to thetop of said table.

2. A bed for sewing machines comprising a bottom adapted to rest upon and be secured to a table, openings in said bottom in alinement with openings in said table and tubular downward extensions of said bottom surrounding the openings therein for preventing oil from passing through said openings on to the top of said table.

3. A bed for sewing machines comprising a bottom adapted to rest upon and be secured to a table, an opening in said bottom a bottom adapted to be secured to a table, an

opening in said bottom registering with an opening in said table and having its margins bounded by a downwardly projecting flange having an oil groove around its inside near its lower edge, said oil groove sloping toward one part of the flange to lead oil thereto, whereby said oil may be discharged clear of said table.

5. A bed for sewing machines comprising a bottom adapted to be secured to a table, and side and end walls, openings in said bottom, and means for preventing oil from passing through said openings on to the top of said table, in combination with a driving wheel guard hinged to the side wall of said bed at one end to swing in the plane of said driving wheel.

6. A metal leak-proof box for incasing the base of a sewing machine, openings in the bottom of said box, the walls of said openings being extended below the surface of the table, and downwardly projecting pipes passing through the table which are adapted to receive holding-down bolts for the sewing machine, thereby securing both machine and box to the table.

7 A metal leakroof box for incasing the base of a sewing achine, one end of said box having a belt wheel-guard hinged thereto to swing away from over the belt-wheel,

said belt-wheel guard being adapted to incase the belt-wheel and moving parts associated therewith, and having an opening in its side for a hand-wheel operating on the outside of said guard.

8. A metal leak-proof box forincasing the base of a sewing machine, one end of said box having a belt wheel-guard hinged thereto to swing away from over the belt-wheel, said belt-wheel guard having a flange constituting a drip edge around the inside of its lower edge, said flange fitting within the side walls of the end of said box.

Signed at St. Louis, Missouri, this 8th day of April, 1915.
